36 Mbit NoBL synchronous SRAM — what the 3.4 ns access buys
That 3.4 ns access keeps the bus timing closure clean on a 167 MHz synchronous interface — no wait-state insertion needed for back-to-back transactions. The 36-bit word width maps directly to a 32-bit data bus plus four parity or ECC bits, common in networking and telecom line-card buffer applications.
Package — 165-ball FBGA, 15 x 17 mm
The device comes in a 165-ball FBGA with a 15 x 17 mm body. Surface-mount only. The fine-pitch BGA requires X-ray inspection after reflow and a moisture-sensitive handling procedure — MSL level should be confirmed from the bag label before the reflow profile is set.
Last Buy — finite window, no official successor
Infineon lists the CY7C1460KVE33-167BZC as Last Buy. That means the manufacturer has announced a final order period; after that date the part will not be produced. No official replacement order code is published for this specific speed and package variant. For a BOM that depends on this exact SRAM, the procurement decision is time-sensitive — secure inventory through the remaining LTB window or qualify a drop-in alternative before the channel dries up.
